Image-sensor data compression

1. A method comprising: by a first computing device associated with an image sensor: accessing image-sensor data generated by the image sensor, wherein the image sensor has a color filter array comprising a first pre-determined number of filter sets, and wherein each of the filter sets corresponds to a single color; splitting the image-sensor data into a second pre-determined number of images, each image corresponding to a portion of the image-sensor data associated with one of the filter sets; compressing each of the images using an image compression algorithm; and sending the compressed images to a second computing device, wherein the second computing device is configured to create an output image based on the compressed images wherein creating the output image comprises: de-compressing each of the received compressed images; generating an interleaved image data by interleaving the de-compressed images; and generating the output image by de-mosaicing the interleaved image data.

2. The method of claim 1 , wherein the image sensor converts light information into electrical data for each pixel.

3. The method of claim 1 , wherein a filter belonging to one of the filter sets passes light information for a corresponding color, wherein each pixel in the image sensor is associated with a filter, and wherein the filter sets in the color filter array are arranged in a pre-determined pattern.

4. The method of claim 3 , wherein each of the images comprises data associated with pixels filtered by filters of a corresponding filter set.

5. The method of claim 1 , wherein the first pre-determined number is equal to the second pre-determined number.

6. The method of claim 1 , wherein the color filter array is a Bayer filter array.

7. The method of claim 1 , wherein the image compression algorithm is efficient with sparse data.

8. The method of claim 1 , further comprising performing a noise reduction on each of the images.

9. The method of claim 1 , wherein generating the output image comprises noise reduction, dynamic range correction, or interpolation.

10. One or more computer-readable non-transitory storage media embodying software that is operable on a first computing device associated with an image sensor when executed to: access image-sensor data generated by the image sensor, wherein the image sensor has a color filter array comprising a first pre-determined number of filter sets, and wherein each of the filter sets corresponds to a single color; split the image-sensor data into a second pre-determined number of images, each image corresponding to a portion of the image-sensor data associated with one of the sets of filters; compress each of the images using an image compression algorithm; and send the compressed images to a second computing device, wherein the second computing device is configured to create an output image based on the compressed images, wherein creating the output image comprises: de-compressing each of the received compressed images; generating an interleaved image data by interleaving the de-compressed images; and generating the output image by de-mosaicing the interleaved image data.

11. The media of claim 10 , wherein the image sensor converts light information into electrical data for each pixel.

12. The media of claim 10 , wherein a filter belonging to one of the filter sets passes light information for a corresponding color, wherein each pixel in the image sensor is associated with a filter, and wherein the filter sets in the color filter array are arranged in a pre-determined pattern.

13. The media of claim 12 , wherein each of the images comprises data associated with pixels filtered by filters of a corresponding filter set.

14. The media of claim 10 , wherein the first pre-determined number is equal to the second pre-determined number.

15. The media of claim 10 , wherein the color filter array is a Bayer filter array.

16. The media of claim 10 , wherein the image compression algorithm is efficient with sparse data.

17. The media of claim 10 , wherein generating the output image comprises noise reduction, dynamic range correction, or interpolation.

18. A first computing device associated with an image sensor comprising: one or more processors; and one or more computer-readable non-transitory storage media coupled to one or more of the processors and comprising instructions operable when executed by one or more of the processors to cause the system to: access image-sensor data generated by the image sensor, wherein the image sensor has a color filter array comprising a first pre-determined number of filter sets, and wherein each of the filter sets corresponds to a single color; split the image-sensor data into a second pre-determined number of images, each image corresponding to a portion of the image-sensor data associated with one of the sets of filters; compress each of the images using an image compression algorithm; and send the compressed images to a second computing device, wherein the second computing device is configured to create an output image based on the compressed images wherein creating the output image comprises: de-compressing each of the received compressed images; generating an interleaved image data by interleaving the de-compressed images; and generating the output image by de-mosaicing the interleaved image data.
